This dataset contains data of mercury (Hg), bromine (Br), iodine (I), Manganese (Mn), sodium (Na) and mathasulphonic acid (MSA) from Svalbard (78° N, 11° E) surface snow (first 3 cm) analysez through ionic chromatography (IC) technique. The two campaigns have been respectively conducted from october 2018 to may 2019 and from october 2019 to may 2020. All the results are shown in ppb.

Spatial variability: validation dataset on pops concentrations in snow (SVAL-POPS) We aim to measure the spatial variability of chosen persistent organic pollutants levels in the snow. The samples will represent three spatial scales: 2-5 m spacing, 0.5-1 km distance, and two sites across Svalbard: Ny Ålesund and Hornsund. These will be compared thanks to a laboratory crosscheck.
